This paper presents a framework for Service Level Management in dynamic, heterogeneous environments for service composition. Assumptions to and the architecture of a framework is introduced that enables risk-aware decisions in dynamic service composition environments. The implementation in the project ValueGrids is described.

This document contains a highlevel description of the QoS classes of service which are recommended for development and eventual deployment across JANET. The recommendations have been formulated on the basis of experience gained in the framework of the JANET QoS Development Project. Two QoS services are described: IP Premium and Less than Best Effort. These complement the regular Best Effort ser...

One of the challenges facing intermodal integration is that the planning framework needed for it lacks appropriate measures of level of service that cut across the modes involved and the connections between them. In this study we develop a framework and a set of metrics of level of service in a multimodal context. We propose a conceptual framework in which we identify the various attributes of ...

* Fraunhofer FOKUS, Berlin, Germany + Swinburne University of Technology, Melbourne, Australia Abstract-Service Level Agreements (SLAs) specify the network Quality of Service (QoS) that providers are expected to deliver. Providers have to verify if the actual quality of the network traffic complies with the SLA. Ideally this should be done without introducing significant additional network load...

In this article, the authors introduce the main ideas around the governance of cross-Cloud application deployment and their related concepts. It is argued that, due to the increasing complexity and nature of the Cloud market, an intermediary specialized in brokering the deployment of different components of a same application onto different Cloud products could both facilitate said deployment a...

This paper proposes to integrate security parameters into the Service Level Specification (SLS) template proposed in the Tequila project to improve SLA-based management of QoS [8, 21]. Integrating those parameters in the QoS part of the Service Level Agreement (SLA) specification is essential in particular for secure multimedia services since the QoS is negotiated when the multimedia service is...

Flexible business processes are a key success factor for enterprises to succeed in globalised markets. The Service-oriented Architecture (SoA) concept is very well suited to support flexible business processes and application systems because capabilities (in form of services) can be composed in the most efficient way to achieve a high level of agility. However, the management of SoA-founded app...

Cloud computing has recently emerged in the landscape of Information Technology as a compelling paradigm for managing and delivering services over the Internet in a performanceand cost-effective way. However, its development is still at its infancy, with many issues worthy to be investigated. In this chapter, we analyze the problem of service level provisioning and the possible strategies that ...

Data breaches are the most serious security breaks among all types of cybersecurity threats. While Cloud hosting services provide assurances against data loss, understanding the security service level agreements (SSLAs) and privacy policies offered by the service providers empowers consumers to assess risks and costs associated with migrating their information technology (IT) operations to the ...

Service Level Objectives (SLOs) describe the desired behavior of a service. They present agreed-upon target behaviors (e.g. capacity, performance, availability, cost) that the clients of a service can expect, and that the service provider can manage against. Both clients and service providers need a way to monitor how a service is doing against its SLOs, and display the result of that monitorin...
